Product Overview

The MCP9808T-E/MC is a Digital Temperature Sensor converts temperatures between -20 and +100°C to a digital word with ±0.5°C (maximum) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for temperature sensing applications. The registers allow user-selectable settings such as shutdown or low-power modes and the specification of temperature event and critical output boundaries. When the temperature changes beyond the specified boundary limits, the sensor outputs an event signal. The user has the option of setting the event output signal polarity as an active-low or active-high comparator output for thermostat operation or as temperature event interrupt output for microprocessor-based systems. The event output can also be configured as a critical temperature output. This sensor has an industry standard 2-wire, SMBus and standard I²C™Compatible compatible (100kHz/400kHz bus clock) serial interface.
  • User-selectable measurement resolution
  • User programmable temperature limits
  • User programmable temperature alert output
  • 200µA (typical) Operating current
  • 0.1µA (typical) Shutdown current
  • I²C/SMBus Compatible 2-wire interface
